Markarians Chain

In the middle of the Virgo Cluster of Galaxies lies a striking string of galaxies known as Markarian’s Chain. The chain, is highlighted on the bottom left with two large but featureless lenticular galaxies, M84 and M86. Above them just left of centre is a pair of interacting galaxies known as The Eyes. The Virgo Cluster is the nearest cluster of galaxies, and contains over 2000 galaxies, and has a noticeable gravitational pull on the galaxies of the Local Group of Galaxies surrounding our Milky Way Galaxy. The center of the Virgo Cluster is located about 70 million light years away toward the constellation of Virgo. At least seven galaxies in the chain appear to move together, although others appear to be superposed by chance.

Of particular note from my light polluted garden is bottom right NGC 4446 and NGC 4447, which are at at staggering 352 and 348 million light years distance respectively.

The annotated image shows the major galaxies present.

From my light polluted garden, need a dark sky site next winter.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
